Had not been on the bike for a while. Decide to take a blast . Put in a new plug mixed up fresh gas. Kicked and kicked finally a little hit then boom a big back fire and the kicker is hanging out of the case. Both the outer and inner case broke. Pushed it back in the shop and walked away. I let it ...

appreciate that! Does anyone know if it's a bolt on?

Hi guys, so after two years into this build (see my other thread somewhere) I cannot get the bike to run or start correctly. It had such a nasty kick back it broke two cases. I have done everything with the jetting from lean to rich and it simply will not start or run correctly except WOT. I even to...

wait a second, which bolts are magnesium? The clutch cover is and that's the only thing I know of that's mag

Adding a decomp gizzmo sure looks easier, and is going to be more effective. You treat the cause, not the symptom.... right? After I get it back together I am going to check the compression. taking the head off and modifying is much easier and since I had these apart I figured I'd beef them up.

you should see the back of the ear, nasty. The back brace will be a gusset type about 5 times the size of the stock gusset. I don;t want this to happen again. it also seems this is one of the weak parts of the design as it is an "ear" just hanging out in space with little support.

Here's the clutch cover brace almost done. You can see where it cracked on the case

So it after close inspection it looks like the cases broke from the downforce not the kickback. I say this by looking at which way they actually cracked. I am going to design some gussets to support the kickstart ear on the case so this doesn't happen again. I'll post some pics when they're done

It seems like 90% of the time its right after being rebuilt. id put money on the splines not being lined up properly.... There is only one way to line up the splines... I've done some calling around and this seems to happen to modified motors. I took out both cases on the right side and I'm thinkin...

I got it all figured out, Jeff at SH really really took care of me! Blinkers/lights here I come :) You did well, I got nothing from them ! S/H harness doesn't have provision for blinkers, did you get a wiring diagram for this ? If so, I'd really like a copy of that . . . . . ? sorry, just saw this....

So before I broke the cases I noticed I sometimes had some decent "kcikback" fron the kickstart. I am just curious, how many of you guys experience this? I am running the electrical from service honda so I am seeing if this is a timing issue potentially

So I found a motor and am in the process of replacing the cases. Has anyone welded up another support bracket by the kickstart gear?

Just got this today and including pics so you can see what kind of shape it is in so far. I'm going to offer it here first before ebay since so many people here have helped with my project:) All I intend to keep is both right main cases and the barrel. let me know what you need and include a fair of...

edit, found what i needed

thanks for the help guys!. anyone have any RH cases for sale?

too much compression or do the cases just get weak over time?

Wow, got to Ride around a bit yesterday and was easy on it since its new. Went to start it today and it completely shatter both right side covers from kick starting. Assuming it was the big compression. Is shattering these cases rare?? Not looking forward to pulling it all apart again after 15 minut...

So I started her up tonight and she ran great but didn't have the chain on. So with regards to the shifter, the bolt comes up from underneath and it hits the frame and the shifter cannot go on with the bolt on as the shaft is slotted. Any ideas? Is there an aftermarket one that would work? thanks! I...
